New SKUs Add Multiple Dolby Technologies

1/18/2010 02:00:00 AM Eastern

Dolby technologies of various stripes appeared in multiple new products here at International CES, where Sony announced plans to offer its first A/V receivers (AVRs) with Dolby Pro Logic IIz and Motorola announced plans to incorporate volume-leveling Dolby Volume technology in a line of cable-TV set-top boxes.

In AVRs, Pro Logic IIz post-processing technology adds a pair of front-height channels to 5.1- and 7.1-channel surround systems.

In cable boxes, Dolby Volume maintains a consistent perceived volume level when channels are changed and a TV program transitions to a commercial. Dolby Volume also dynamically and automatically compensates for the human ear's lower sensitivity to bass and treble sounds as volume levels decrease.

Dolby Volume already appears in audio products from ARCAM, Harman Kardon, Sherwood, Bryston, Emotiva, Parasound, Onkyo and Integra. In TVs, Toshiba added Dolby Volume to TVs last year and added the techno logy to its new Toshiba REGZA series LCD televisions here at CES, Dolby said.

In cable boxes, Dolby Volume will appear in Motorola's DCX family of set-top boxes for the North and Latin American markets. The currently available DCX3400 HD-DVR and DCX3200 HD can be updated with Dolby Volume by cable operators. The DCX700 and DCX3300 HD set-tops will ship with Dolby Volume included.
